You first simplify
tan(x) = cos(x)/sin(x) and cot(x) = sin(x)/cos(x)
Then you plug that in and then you simplify even more
Answer:
(30, 90) is a viable solution
(50, 160) is a nonviable solution
Step-by-step explanation:
Answer:
6.52
Step-by-step explanation:
<u>Answer:</u>
x = 3, x = -3
<u>Step-by-step explanation:</u>
x² - 25 + 16 = 0
⇒ x² - 9 = 0
• Add 9 to both sides:
⇒ x² = 9
• Square root both sides of equation:
x =
x = ± 3
x = 3 and x = -3
